چکیده

Partial Least Squares (PLS) based Structural Equation Modeling (SEM) has become increasingly popular in Management Information Systems (MIS) research to model complex relationships and to make valid inferences from the restricted sample to the larger population. Given the larger goal of creating generalizable theories in MIS research, we argue that the lack of model selection criteria in PLS that penalize model complexity might be causing researchers to select unnecessarily complex but highly fitting models that may not generalize to other samples. We introduce several Information Theoretic (IT) model selection criteria in the PLS context that penalize model complexity but reward high fit, and therefore guide researchers to select a parsimonious and generalizable model. In this Monte Carlo study, we compare their performance to the currently existing PLS indices, in selecting the best model among a set of competing models under various conditions of sample size, effect size and data distribution.

Consistent Partial Least Squares Path Modeling

This paper resumes the discussion in information systems research on the use of partial least squares (PLS) path modeling and shows that the inconsistency of PLS path coefficient estimates in the case of reflective measurement can have adverse consequences for hypothesis testing. To remedy this, the study introduces a vital extension of PLS: consistent PLS (PLSc). PLSc provides a correction for...

The Use of Partial Least Squares Path Modeling in International Marketing

The advent of structural equation modeling (SEM) with latent variables has changed the nature of research in international marketing and management. Researchers acknowledge the possibilities of distinguishing between measurement and structural models and explicitly taking measurement error into account. As Gefen, Straub, and Boudreau (2000, p. 6) point out, ‘‘SEM has become de rigueur in valida...
